Is it possible that devices originally installed before the multiple-ESP support was introduced don't have grub-efi/install_devices configured at all?
This was way before my time, but since that key doesn't exist in Debian (I think Debian grub only has install_devices for grub-pc and EFI just goes by ESP mountpoint), I have a hunch that this might be the case. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2083176 Title: grub-efi install device being prompted on upgrade, despite only /boot/efi being an option.
